terminal output from a bad run

After 7abf4432a7d [1], the PlayOnline Viewer runs and seems functional, but
only shows a black screen.

There doesn't seem to be anything out of the ordinary in the terminal output,
aside from a flood of:

libEGL warning: FIXME: egl/x11 doesn't support front buffer rendering.

Last tested at 'wine-10.17'.

Thank you!

--- Comment #2 from Krzysztof Sobiecki  ---
This is a MESA warning:
libEGL warning: FIXME: egl/x11 doesn't support front buffer rendering.
In dri3_flush_front_buffer at src/egl/drivers/dri2/platform_x11_dri3.c
-   /* There does not seem to be any kind of consensus on whether we should
-    * support front-buffer rendering or not:
-    * http://lists.freedesktop.org/archives/mesa-dev/2013-June/040129.html
-    */

dri3_flush_front_buffer doesn't do anything so it might be a reason it shows
black screen...
